The Enigma machine was invented by German engineer Arthur Scherbius at the end of World War I. [4] The German firm Scherbius & Ritter, co-founded by Scherbius, patented ideas for a cipher machine in 1918 and began marketing the finished product under the brand name Enigma in 1923, initially targeted at commercial markets.

The Enigma machine looked like a typewriter in a wooden box. He called his machine Enigma which is the Greek word for "riddle". Combining three rotors from a set of five, each of the 3 rotor setting with 26 positions, and the plug board with ten pairs of letters connected, the military Enigma has 158,962,555,217,826,360,000 (nearly 159 ...
In cryptography, the clock was a method devised by Polish mathematician-cryptologist Jerzy Różycki, at the Polish General Staff's Cipher Bureau, to facilitate decrypting German Enigma ciphers. The method determined the rightmost rotor in the German Enigma by exploiting the different turnover positions.
Marian Adam Rejewski (Polish: [ˈmarjan rɛˈjɛfskʲi] ⓘ; 16 August 1905 – 13 February 1980) was a Polish mathematician and cryptologist who in late 1932 reconstructed the sight-unseen German military Enigma cipher machine, aided by limited documents obtained by French military intelligence.
The title refers to the French, British and Polish teams which worked on breaking the Enigma cipher, known by shorthand as "X", "Y" and "Z", respectively. The Enigma cipher, produced by the Enigma machine, was used from the 1920s to the end of World War II by Germany—later Nazi Germany—for military and other high security communications.
The machine was developed by British mathematician Alan Turing, and it was used to decode messages sent by the Nazi military. Bought for $115, a WWII Enigma machine sells for $51,000 Skip to main ...
The Enigma-M4 key machine Key manual of the Kriegsmarine "Der Schlüssel M". The Enigma-M4 (also called Schlüssel M , more precisely Schlüssel M Form M4 ) is a rotor key machine that was used for encrypted communication by the German Kriegsmarine during World War II from October 1941.
